 on the fourth abdominal segment is yellowish white and the 

 basal portion of the abdomen has not the reddish hairs. 

 Another specimen of B. iridis, taken at Monument Rock, 

 tSanta be Canon, 8000 feet, at Rudbeckia laciniata, Aug. 11 

 {Ckll. 4425), has the hair on the sides of the first abdominal

Bombus monardce^ sp. n. 



Resembles fervidus, but the yellow is not so bright, the 

 third submarginal cell is more narrowed above, and the hair 

 of the face and vertex is yellow, with some black on the sides 

 of the vertex and on the front. The pubescence is rather 

 longer and looser than in fervidus, borealis, or sonorus ; the 

 hair on the pleura is yellow, not black as in borealis and 

 sonorus ; the wings are only stained with brown, not dark 

 brown as in sonorus.
